Question

What is pulse code modulation in digital communication?

Answer 1

Pulse code modulation in digital communication:

1. It is a digital technique that is used to convert analog information into binary variables.
2. Its output is a binary sequence and that is $1s,0s$.
3. Each binary code represents the amplitude of the signal.
4. It is that type of modulation in which signals are transmitted in the form of pulses. In short, it is written as PCM.
5. It is used in long-distance communication. Like satellite systems and space communication and telephony.
